Find the area and perimeter of the circle with the following :

Radius= 2.8 cm

###### Advertisements

#### Solution

Area of the cirde = πr^{2 }

`= 22/7 xx 2.8 xx 2.8`

= 24.64 cm^{2}

Perimeter of the circle = 2πr

`= 2 xx 22/7 xx 2.8`

= 17.6 cm

Therefore, Area= 24.64 cm^{2} and Perimeter= 17.6 cm
